this is getting downloaded as I type. I was reading The Skinny and it announced that Forever 21 just launched an app for the iPhone/iTouch/Smart Phone (or whatever gadget you possess). You can shop, scope out the new arrivals, catch up on The Skinny, and browse through the lookbook for inspiration. This will definitely be used every day by me!
Oh, and the best part? IT'S FREE :)
You've gotta love Forever 21. I'm browsing through the app right now and I'm already in love. It takes you to their facebook and twitter pages too.
